This study is an overview of the life of king Manasseh. He rebelled against his upbringing and led the people of Judah astray. He caused the people to sin worse than the people that God drove out of the land in the beginning. His killed many prophets -- possibly Isaiah. God pronounced judgment and sent the Assyrians to deal with Manasseh. He humbled himself and turned back to God. However, he was not able to fully undo his sin. The people continued to worship in the high places.
